I'm sure if you describe loosely how you look we can help.
Height
Dress size
Body shape (roughly) eg I'm an apple - big boobs and belly but slim arms and legs and virtually non-existent bum!
Skin, hair and eye colouring
Age (not because I believe in X age shouldn't wear z but it'll give us an idea of your 'fashion era' and what you'd likely be comfy in)
Any other considerations - eg problem areas you want to disguise, disabilities or health conditions that affect style or fastenings etc
Also
Preferred heel height (not cos we'll necessarily recommend shoes unless you ask, but certain styles work best with certain heel heights)
Favourite colours (wearing and make up)
And... You've answered some of that already.
I'm also red hair white skin (but considerably larger)
There's actually very few colours you'd struggle to wear (certain shades of red, pink, purple depending on shade of red)
I wear green, brown, blue, neutrals (but not nude - not a fan), purple, burgundy mostly.
That blue/green savella dress is gorgeous.
But I have tbh and say given your figure I'd say consider a wiggle dress too.
